It is said that GPS tracking devices are often installed in some cars. Some people are afraid of GPS. The most common mobile phone jammers in life are very common. Now you can see that jammers are used in many places. The positioning function of GPS can be hindered by transmitting interfering radio waves with the same wavelength as the radio waves of GPS satellites. I confirmed that the radio waves emitted by the equipment are very weak and are within the range of weak radio waves defined by the Radio Law.
This is a cell phone jammer device that can block radio waves to the car GPS receiver. Mobile phone jammers are widely used in the market. If the device is jammed, it means that the phone is out of service and cannot be used. There is a portable cell phone jammer that supports this type of device, and it also includes a car charger, so you can charge while running.
You need to realize that this is an advanced anti-tracking technology. There are many GPS tracking applications that currently have a location tracking function. Many times you do not notice it. Someone is constantly monitoring your activities, and personal privacy may have been leaked. There are some GPS jamming devices that can escape tracking, and the radio waves of smartphones can be cut off.
